Our Corolla, NC technicians sample near supply and return vents specifically, which a standard single-room test would never catch.
Every result comes with a plain-language walkthrough connecting the data back to what you're actually experiencing at home. We'll also suggest a sensible next step, whether that's duct cleaning or a physician conversation.
Four reasons Corolla property owners trust us with this specific job.
A contaminated duct system can spread spores throughout an entire Corolla home via the HVAC system. This approach catches whole-house circulation issues a single-room test would miss.
We don't process our own samples — an independent lab handles every Corolla analysis, keeping results unbiased. You can verify the lab's accreditation directly if that matters to you.
Indoor versus outdoor comparison sampling helps determine if your home is actually contributing to allergy season. This context shapes which testing method we recommend.
Reports include actual spore counts and species data, not a vague pass or fail. We're glad to explain the numbers directly with you over the phone.
